I am thinking about to do the same to my KTM 350 EXCF... instead of doing a top end and valve I will just make it electric! Please show how you installed the electric motor and brackets! Good Video!
I got the bike and the owner had installed the motor. It wasn't quite up to what I wanted, so I redid it. But I do have some pictures. This isn't a good forum for sharing info and pics. Go to the Electricdirtriders.com forum ( it used to be the Altaownersforum.com) begin a conversation with me and I will give you a lot of photo data. One of my upcoming projects is a 2021-2022 works KTM bike from a friend with all kinds of good stuff on it . It's pretty much the same as the 2017.
Mighte.me carries sprockets for the QS138 70H V3 motor. They have 13,14,15t. I am currently using 13 x 49 on KTM 150SX, and YZ250F electrics with the QS V3 motor. Trench digging power, and almost 60MPH 100KPH
No, we were planning on watercooling the Controller if we went to 450A, but the owner is way happy with 350A, so we never put the system in and we took the radiators off. They do have a QS 138 90H motor that is water cooled.
Are you planning to plumb the radiators into the controller (and/or motor)? It feels like these bikes with water cooling already on them are just begging to use those on these applications. I haven't found too many motors that are plumbed yet (and didn't know if motor or controller is better to cool). I hope there are more enclosures and "kits" to start doing clean conversions like this. I have a 2006 KTM 525EXC that it would be nice to convert.
This bike has been ridden for the last year. The owner is so happy with it, and all the delays with his Stark delivery, he is probably going to cancel his Stark order. We had originally planned to water cool the controller. Surprisingly we haven't had the motors overhead on any of our builds, yet!!! (Well over 20 bikes that we have done) But if you run the EM260 controller over 400Amps, it will overheat. We haven't installed the Controller cooler yet, since this owner , and most people with this setup, don't feel the need for more HP than the 350-390 amps give you. I am building a 2008 KTM 250SX right now. I should have a UA-cam posted soon. Message me (Donald Cox) thru ElectricDirtRiders.com and I'll post a bunch of the images up there for you
Hi, I found out here on UA-cam that the QS138 engine has aluminum terminals, and the wires are made of pure honey, and they have not been cleaned of varnish, this leads to ignition of the engines. Can you check how you are doing with the q s 138 engine, the same? As for the long-range drive controller, there are aluminum studs inside that are used to connect phase wires and a battery, this is also bad
Hello I’m in the process of doing the same thing to a Suzuki rm125 but I’m having a hard time figuring out what gauge wire and what connectors to use with my battery I’m going to be using 3 72v 40ah 170amp batteries in parallel they come with 10 or 12 gauge wire, and xt90 connectors I’m new to this stuff, so I’m not sure if that will work, but I feel like it won’t
for a 125cc bike (2016 Tao Tao Db17) do you recommend a 200sp or 260sp controller? My main goal is to stay on a budget and hit 50 miles an hour at least. Will 240 amps be enough for the battery (72v 40AH 240/350AMP ANT battery?
An em200 or 260 will both get you to 50mph. 200-250Amps moves a full size bike good. I find about 275-300A is a good level for the track, but that would require a little larger battery, and the EM260 controller to get that.
Great looking build! I’m seeing plenty of people using the QS138 V3 but am curious where everyone’s getting the wiring harness to connect them to throttle/display etc? Or is this just another part of the build you have to make yourself?
If you buy your kit from ElectroandCompany.com the harness, switches, and throttle and come pre made. Literally, bolt your motor in, mount your controller, hook up wiring harness with switches and throttle, and a battery, and drive it away.
Thank u for ur works and sharing experience! In qs 138 70 h motor can i use 20 ah 70 v battery? Is there other requirement rated current etc for effecrive run of motor?
Yes, you need to use cells that can put out a lot of current. a 72V battery with 7 Sony VTC6 cells will put out 210A . But it is only rated at 15AH . This battery with the KX100 bike gets about 15miles of range. not all 3000mah cells can put out 30A peak discharge, but the VTC6 cells do.
Dear colleague could you say what sprocket do you use? For KTM and KX100? I try calculate by video - front 520 T14 and rear 520 T50??? What speed maximum? It is good for big hills? I'm doing byke at Kayo T4. Thanks :)
On the Kawasaki I have 15 - 49, and the top speed at 200A is 53mph. On the KTM, I have 13 - 50. The wheel is bigger, and I think the EM 260 controller will give the same RPM, maybe more with the 350A, but I should have it running in a week or so, I will try to remember to test the speed and let you know.
Don, another clean build sir. Question why don’t you program the controller and motor through a laptop? Wiring is pretty straight forward with tons of options you can add like 3 speed switch plus boost, reverse, throttle response when you order through QS they provide the programming cable. Also look at SPIM08HP cells 8ah and 200amps continuous love your builds. Definitely gave me motivation on my KX100E I finished
Thanks for the compliments. Yes I do have the computer hookup for these controllers, and Austin at ElectroandCompany.com has been a great help on making adjustments. We've pushed the regen up to 15% and it works a lot better on the track. And we have adjusted the 3 speeds a little different. Of course we left mode 3 or Boost, we left at 100%. It rips in that mode. Austin had the Mode 1 and Mode 2 at 50% and 75%, we change them to 25 and 66% The original setting from ElectroandCompany.com are great, this is just some fine tuning. I have just started to hear about the SPIM08HP cells. I am going to look into them. It looks like a lot simpler building with them
The SPIM08HP cells are insane it never stops pulling. I’m working on a clean looking battery box for them now but I think I’m going to order more cells to have a second battery pack. The mode settings I’m curious about those sound like a great combo mine are 1-55/2-75/3-100 boost 120% but I really like 1-@25% and 2-@65% because I can’t tell the difference between modes but doing it that way would make a world of difference. Not sure where you are located looks like AZ I believe I heard Mesa In one of your videos. I’m In SoCal but my oldest son is in buckeye maybe next time I’ll bring my KX100E and we can ride
@@GOAT-iz3uo I tried to answer this twice last night, but I don't think they got sent... I use ABS or PVC sheets for my battery boxes, and form them with a Harbor Freight Plastic Welder www.harborfreight.com/welding/soldering-plastic-welding/plastic-welders/plastic-welding-kit-with-air-motor-and-temperature-adjustment-96712.html I like the 25 - 66 - 100, especially with the 350A, it gives good steps. I do live in Arizona, in Lake Havasu City, and yes bring your Kx100E, the desert is 2 blocks away. I am going to Pala for the national, and I will have my KX100E there. Come on out to the races. There are unofficial pit races on Friday night. A friend from Yorba Linda will be there also, and he has built 2 electric CR250F bikes. But later if you want to stop out here in Lake Havasu, we could build a box real quick for your battery.
Looking at going with this same combo from Electro and Co. As I know nothing about building batteries, I'll likely have one made. What are your thoughts on the performance so far? Ride time? Actually didn't know about the regen, so that's a nice bonus! Thanks for sharing, Don!
I would recommend the battery that ElectroandCo has. The 72V 25AH from Ion Lithium is a great choice. I think they are a little over rated at 25ah, 20S6P P42A cells should give you about 20mile range. We have gotten consistently 25 miles out of that combo at 200A max out of 20S8P Molicel P42A battery. The Regen is really easy to adjust. It will come at about 7%, but they can set it to any number, and we have them set it at 15%. The performance on the smaller bike with the 200A limit is phenomenal. There is a full size KTM running with this combo, running the 450A and it truly is Ludacris. Here are 2 of my builds with the 200A controllers. The 2 Kawasaki's. ua-cam.com/video/NgBPAgUQaFw/v-deo.html
Gnarly build and I can tell it's a ripper 🤙🏽
Also, great meeting you at the fully charged event a couple weeks back. Keep it up!
Thanks. Which bike did you have at Fully Charged? Are you going to the next one. I can't make it.
@@dcoxryton I had the razor SX500 build w/street tires. I don't think I'll be able to make it since we just moved to AZ last month ..
@@bolectric Weren't you moving to the Glendale Az Area. Are you enjoying the monsoons? man we got a lot of rain up here yesterday
@@dcoxryton We actually moved to Queen Creek =). Also enjoy the monsoons especially since it brings the heat down 😅
Wild build
Thanks. This guy has been riding this bike now for 2 years. and He loves it . I am now doing a 2022 KTM.

Hey what a great build! I’m tryin to get mine in a 2011 sx250 where did you get a 520 sprocket for it?

I noticed that a radiator is installed, is this water cooling for the qs 138 engine? There is a video about this change?
No, we were planning on watercooling the Controller if we went to 450A, but the owner is way happy with 350A, so we never put the system in and we took the radiators off. They do have a QS 138 90H motor that is water cooled.
any idea why it tops out at 60mph when its running 25-30 kw?

We have found the Votol controllers are the easiest to program, and most reliable.
This is the same motor that is in your KX80 correct? How do you like this motor compared to the XE2 in your Yamaha? Thank you
